Hello.
If Speed = Distance ÷ Time then Time = Distance ÷ Speed
The time taken for the first 90 miles is, 90/x
The time taken for the second 90 miles is, 90/1.5x
The time for the complete journey = 90/x + 90/1.5x = 450/3x = 150/x
Have a nice day
Hey, i’d love to help you but there seems to be a typo in your equation because a minus sign (or negative sign) can’t be raised to the power of 3.
Step-by-step explanation:
d=2r.
50=2r
r=50/2
r=25cm.
circumference of circle =2πr
=2×22/7×25
=157cm(approx)
area of circle=πr²
=22/7×(25)²
=704cm
Answer:
(14-9i)+(2+3i) = 16-6i
Step-by-step explanation:
We need to find the equivalent of (14-9i)+(2+3i).
We need to add the two expressions.
(14-9i)+(2+3i) = 14+2 -9i+3i
= 16-6i
Here, the real part is 16
The imaginary part is -6
Hence, the required answer is equal to 16-6i.
